I'm running an up-to-date Fedora 23 system (kernel-4.4.9-300.fc23.x86_64) and am using an RPM for the DisplayLink driver based on
https://github.com/hadess/displaylink-rpm.
Using this, my second monitor, attached through DisplayPort on the DisplayLink D3100 isn't recognized. Settings -> Display (xfce4-display-settings -- I run XFCE desktop) doesn't mention the monitor at all.
I can see that the evdi module is loaded, and I didn't see any errors in the logs.
Does anybody have any ideas what can be wrong and what I can try?
Attached the output from the SupportTool.
